The usual GCC stuff works. ie:

#define PACK_STRUCT_FIELD(x) x __attribute__((packed))
#define PACK_STRUCT_STRUCT __attribute__((packed))
#define PACK_STRUCT_BEGIN
#define PACK_STRUCT_END

I believe the BEGIN/END stuff doesn't apply to GCC, so the above definition is 
fine.

(I've tested this with GCC on PPC405, and ARM920T)
